This rotating magnetic field has a speed which is known as the synchronous speed.. This rotating magnetic field induces the voltage in rotor bars and hence short-circuit currents start flowing in the rotor bars.

Induction motor - Wikipedia

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage …
